Studying the behavior of machine parts and components, in general and standard ones in operational and critical conditions, from the surface and volumetric strength, stiffness, operational life stability and energy efficiency point of view. Determination the load essential for the analysis of the operational capacity of machine elements and components,based on analytical, numerical and experimental methods.

Students will be able to: use the scientific literature on selected areas from the scope of the Course; independently solve a scientific-research problems from selected area (making of appropriate analytical, numerical and experimental models); individually or as a team member, to write scientific research papers; to transfer knowledge and skills to others.

Tolerances and fittings. Behavioral problems of machine elements in static and dynamic operational mode. Axles and shafts. Universal (Cardan) joints. Sliding and rolling bearings. Threaded joints. Power transmitions (frictional, gear, belt, chain) - calculation and simulation. Threaded transmition. Couplings. Springs. Inseparable joints.

Service life and strength testing of Machinery parts and systems in laboratory conditions.
